2.1.1 Power Input [J7] [J3] with LED for Status [LD4][LD5]

The EVM supports two separate power input connectors [J7] [J3], either of which can be used to power the system. (Note both should not be used as the same time, as connecting power supply outputs together can cause damage to the EVM and/or power supplies.) The input can accept a wide range of voltages (20 to 48 VDC). The exact power required for the EVM is largely dependent on the application and connected peripherals. The recommended supplies are listed in Table 2-1. There are many power supply manufacturers and models available in the market, and it is not possible to test the EVM with every combination.

Table 2-1 lists a few recommended supplies that have been tested with the EVM.

Table 2-1 Recommended External Power Supply
DigiKey Part# Manufacturer Manufacturer Part #
SDI120-24-UC-P51 CUI Inc. SDI120-24-UC-P51
SDI120-48-UC-P51 CUI Inc. SDI120-48-UC-P51

Connector [J7] is a four pin DIN power input connector. This connector mates with the recommend supplies listed in Table 2-1. Connector [J3] is a two pin power input connector, and is used to power the EVM from bench power supply(s) or similar equipment. The EVM kit includes a cable assembly for connecting the bench supply (via banana plug) to the [J3] power input.

A green power led [LD4] will be illuminated when a valid power source is connected to either power input. A red power led [LD5] will be illuminated when a power source not within the correct voltage range (less than 22 VDC or greater than 52 VDC).
